Telling the same story in different places

@sandolinic

Color should be used meaningfully

• Use natural colours • Use intense colours only when

you wish to draw attention to specific data.

• Use the same colour, except when colour differences are needed to indicate differences in the data or encode a dimension

• Use a single, neutral background colour (if needed at all)

• KEEP IT SIMPLE AND CONSISTENT

Not only for deco ☺
